/* ==================================================================
   Run for the Mind - design system (loaded first on every page)
   Applied from the organiser's DESIGN.md (a photography-first athletic
   system): white canvas, one black ink, one soft grey surface, a single
   towering uppercase display tier (Bebas Neue, the file's named stand-in
   for the proprietary display face) and a quiet 12-16px interface tier
   (Inter). Pill buttons, square flat cards, no shadows, hairline
   dividers; colour comes from photography, red only for errors and
   placeholders. Token names from earlier versions are kept as aliases
   so every page stylesheet follows.
